Arancinis (Italian rice balls) , breaded beef and chicken cutlets, stuffed artichokes, a pot roast, stuffed mushrooms, stuffed peppers, I’m basically listing off everything my Italian mother in law has ever served me... they all kind of work well.
I attended a wedding over the weekend and they had Italian for the meal. They had roasted potatoes, vegetables and chicken skewers, a salad, a couple different kinds of pasta and meat. For appetizers they had a wood fire pizza truck (yum!) and they had some Italian cold cuts, olives and something else that I can't remember, it looked like a meatball but it was breaded and I tji k it had cheese and spinach in it.
Does your pasta have any meat in it? Some chicken & meatballs would be needed to make it a meal. As far as sides, I think the salad and bread sticks is plenty. You could add some roasted veggies if you wanted to but I do not think its necessary.
